July 27, 2020 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) Region 5 is publishing a direct final Notification of Deletion of the Scrap Processing Co., Inc. Superfund Site (Scrap Processing Site or Site), located in Medford, Wisconsin, from the National Priorities List (NPL). The NPL, promulgated pursuant to Section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This direct final deletion is being published by EPA with the concurrence of the State of Wisconsin, through the Wisconsin Department of Natural Resources (WDNR) because EPA has determined that all appropriate response actions under CERCLA, other than operation and maintenance, monitoring institutional controls, and five-year reviews, have been completed. However, this deletion does not preclude future actions under Superfund.

The FAA is superseding Airworthiness Directive (AD) 2018-08-02 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan engines. AD 2018-08-02 required initial and repetitive ultrasonic or visual inspections of the intermediate- pressure compressor (IPC) stage 1 rotor blades, IPC stage 2 rotor blades, and IPC shaft stage 2 dovetail posts, and removal of any cracked parts from service. This AD requires new inspections based on updated inspection thresholds and intervals for these IPC parts. This AD also adds an optional terminating action, amends the asymmetric power condition for engine inspection, and requires an inspection after a cabin depressurization event. This AD was prompted by IPC blade separations resulting in engine failures. Subsequently, the manufacturer identified the need to add new inspections and an optional terminating action, amend the asymmetric power condition for engine inspection, and require an inspection after a cabin depressurization event. The FAA is issuing this AD to address the unsafe condition on these products.

In this document, the Office of Engineering and Technology dismisses Encina Communications Corporation's Petition for Reconsideration for the final rule published in the Federal Register on May 26, 2020. A Petition for Reconsideration of this order must have been filed within thirty days, i.e. on or by June 25, 2020, to be considered timely. However, the Petition was filed on June 29, 2020, four days late. We therefore dismiss it.

The FAA is superseding Airworthiness Directive (AD) 2018-18-02 for certain Austro Engine GmbH model E4 engines and all Austro Engine GmbH model E4P engines. AD 2018-18-02 required replacement of the timing chain and amending certain airplane flight manuals (AFMs) to limit the use of windmill restarts. This AD requires amendment of certain existing AFMs to limit the use of windmill restarts and removes the timing chain replacement requirement in AD 2018-18-02. This AD was prompted by reports of considerable wear of the timing chain on the affected engines. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2016-07-13 and AD 2018-03-22 which apply to certain GE Aviation Czech s.r.o. M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, and M601F model turboprop engines. AD 2016-07-13 required inspection of the engine power turbine (PT) disk and, if found damaged, its replacement with a part eligible for installation. AD 2018-03-22 required the removal of certain engine PT disks identified by part number (P/N) installed on the affected engines. This AD requires an inspection of the engine PT disk and, if found damaged, its replacement with a part eligible for installation. This AD also requires the removal of certain engine PT disks identified by P/N installed on the affected engines. This AD was prompted by the discovery of damage to certain engine PT disks and a review by the manufacturer that determined that certain engine PT rotors have less overspeed margin than originally declared during product certification. This AD was also prompted by the manufacturer identifying additional P/Ns and serial numbers (S/Ns) of engine PT disks affected by damage or non-conformity since publishing AD 2016-07- 13 and AD 2018-03-22. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A, Trent 1000-A2, Trent 1000-AE, Trent 1000-AE2, Trent 1000-C, Trent 1000-C2, Trent 1000- CE, Trent 1000-CE2, Trent 1000-D, Trent 1000-D2, Trent 1000-E, Trent 1000-E2, Trent 1000-G, Trent 1000-G2, Trent 1000-H, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan engines. This AD was prompted by the manufacturer identifying 38 low-pressure compressor (LPC) front cases that have non-optimal properties that could inhibit their ability to contain certain engine failures. This AD requires removing the LPC front case from service and replacing it with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

The Coast Guard is changing the operating schedule that governs the Tammany Trace swing bridge across Lacombe Bayou, mile 5.2, at Lacombe, St. Tammany Parish, Louisiana. This bridge will open on signal if at least two hours notice is given. This rule is being changed because there are infrequent requests to open the bridge. This change allows St. Tammany Parish to open the bridge when needed by Tammany Trace park officials.

The Commission is acknowledging a recent filing requesting the Commission initiate a rulemaking proceeding to consider changes to analytical principles relating to periodic reports (Proposal Four). This document informs the public of the filing, invites public comment, and takes other administrative steps.

The Environmental Protection Agency (EPA) is proposing to approve negative declarations submitted to satisfy the requirements of the Emission Guidelines and Compliance Times for Municipal Solid Waste Landfills for the City of Philadelphia, located in the Commonwealth of Pennsylvania, and the District of Columbia. The negative declarations certify that there are no existing municipal solid waste landfills in the City of Philadelphia or the District of Columbia that are subject to the requirements of 40 CFR part 60 subpart Cf.

The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submission from the State of Washington (Washington) demonstrating that the SIP meets certain Clean Air Act (CAA) interstate transport requirements for the 2010 1- hour Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS). In this action, EPA is proposing to determine that emissions from sources in Washington will not contribute significantly to nonattainment or interfere with maintenance of the 2010 SO2 NAAQS in any other state. Therefore, EPA is proposing to approve Washington's February 7, 2018 SIP submission as meeting the interstate transport requirements for the 2010 1-hour SO2 NAAQS.

This action amends, with modifications to reflect changed conditions in Libya and the associated risks to U.S. civil aviation safety, the Special Federal Aviation Regulation (SFAR) prohibiting certain flight operations in the Tripoli Flight Information Region (FIR) (HLLL) by all: United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.- registered aircraft for a foreign air carrier; and operators of U.S.- registered civil aircraft, except when the operator of such aircraft is a foreign air carrier. This action incorporates the FAA's prohibition on U.S. civil flight operations in the territory and airspace of Libya at all altitudes contained in Notice to Airmen (NOTAM) KICZ A0026/19, into the SFAR. In addition, the FAA remains concerned about the safety of U.S. civil aviation operations at altitudes below Flight Level (FL) 300 in those portions of the Tripoli FIR (HLLL) that are outside the territory and airspace of Libya because of the hazards described in the preamble to the FAA's March 2019 final rule. Accordingly, this final rule also prohibits U.S. civil flight operations below FL300 in those portions of the Tripoli FIR (HLLL) outside the territory and airspace of Libya. This action also extends the expiration date of the SFAR from March 20, 2021, to March 20, 2023. Finally, the FAA republishes the approval process and exemption information for this SFAR, consistent with other recently published flight prohibition SFARs, and makes minor administrative revisions.

Under the Toxic Substances Control Act (TSCA), the Environmental Protection Agency (EPA) is finalizing amendments to the significant new use rule (SNUR) for long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances that were proposed on January 21, 2015; an amendment to a SNUR for perfluoroalkyl sulfonate chemical substances that was proposed on January 21, 2015; and an amendment to make inapplicable the exemption for persons who import a subset of LCPFAC chemical substances as part of surface coatings on articles, which was proposed on March 3, 2020. This final rule requires persons to notify EPA at least 90 days before commencing the manufacture (including import) or processing of these chemical substances for the significant new uses described in this notice. The required significant new use notification initiates EPA's evaluation of the conditions of use associated with the significant new use. Manufacturing (including import) or processing for the significant new use are prohibited from commencing until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required in association with that determination. As with any SNUR, this final rule excludes ongoing uses. Ongoing uses cannot be subject to a SNUR.
